About our mastic sealing in Four Elms

Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. We work on communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints, and the failures we’re asked to look at most are the same joint failures repeated across a portfolio and old repairs sealed over failed mastic. Searching for sealant specialists in Four Elms? We’ve been sealing commercial buildings since 2005.

In and around smaller places like Four Elms, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

When to call us in Four Elms

Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.

Any of the following is a good reason to get the joints checked over:

  • No planned programme for sealant
  • Movement joints with sealant missing
  • Window mastic that has split and shrunk
  • Communal area joints that look neglected

Older buildings near Four Elms, from historic houses such as Chartwell, 2 miles north of Four Elms, to more modest stock, need compatible products when frames are resealed.

Comparing quotes

  • What site paperwork they can supply
  • Health and safety accreditation such as CHAS
  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen

Choosing a commercial sealant contractor

What the job involves on each surface

External movement joints

External movement joints take up expansion and contraction. Once that sealant goes, rain can reach the wall.

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. A planned programme suits multi-building portfolios.

Questions we’re asked in Four Elms

Can you quote for mastic across several buildings in and around Four Elms?

Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.

Is Four Elms off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Will residents or tenants be disturbed?

Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.

Can you take on resealing for a block portfolio?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

What happens if it’s left?

Sealing over failed mastic looks tidy for a while. It doesn’t bond and normally fails within a short time. Cutting out and resealing properly does it once. Converted and older buildings near places like Four Elms tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • One number for every site we cover
  • Products installed to the manufacturer’s instructions
  • Matching to RAL references, product permitting
  • 12-month guarantee on workmanship

See what affects the cost and how we’re accredited.

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Building owners, agents and FMs in Four Elms

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Four Elms can sit alongside others in a wider programme.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Rural sites near Four Elms may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

Frames, entrances and external joints in Four Elms

Rainfall across the South East, Four Elms included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.

If your remit includes a building such as Four Elms Primary School, frame and door mastic can be programmed for the holidays. If you are responsible for a building such as Congregational Church, frame and door mastic needs the same attention as any other property.
